OK, so I have a time machine backup of my Powerbook G4 (the Powerbook is mia), and my MBP is in the mail. I'm wanting to restore from the Time Machine drive. Is this as easy as telling Migration Assistant to do this, or are there issues I should watch out for?
Am I going to run into issues with PPC apps? Should I reinstall my major apps that are Universal, or is that automatic?
Thanks for the help!

In theory it works, in reality, not so well. You can use MA for your data, but reinstall your apps from their install disks/packages.

It just works.
I've restored from Time Machine (data only, do not copy the whole drive!) once and used regular Migration Assistant to go from a PowerPC-based to an Intel-based machine twice. Migration Assistant has yet to fail on me.
The only potential hazards are kernel extensions which you have installed for -- say -- an old USB modem or some (PowerPC-only) Preference Panes.
What you cannot do is to `clone' your PowerPC installation, because it won't boot on Intel hardware. Instead, install OS X on your new machine and then use Migration Assistant to migrate your data using either your old computer or your Time Machine drive as a source.
I recommend you install all apps from scratch, because most of them have since been updated. Pretty much every app comes as a universal binary these days, so there is no need to live with PowerPC apps anymore.

I don't suffer from insanity, I enjoy every minute of it.

I second the "it just works". I went from Powermac G4 with data/users to a Macbook (see sig for both) via firewire, I imagine it will be very similar to the Time Machine backup with Migration Assistant.
And yes, reinstall apps from scratch. Consider it a cleansing of most ppc apps to help keep your intel machine speedy.

Thirded. MA works very well.
If you encounter something that didn't transfer well (how Apple's own iWork apps cannot survive MA is beyond me) you can still re-install these apps after you transfered all your stuff with MA.
You will re-install many apps anyway because you want UB or Intel versions rather than your old PPC versions.
And as OreoCookie correctly pointed out you need to take care that things like kernel extensions that are geared towards one instruction set (like PPC) don't screw up your install on a new platform (Intel). But as long as you double-check the usual suspects (kexts, preferences) you'll be fine.
